Vision Measurement Method Based on Image Mosaicing for Micro-part
Shenghua Ye · Yuhang jice jishu · 2006
In order to increase the detecting accuracy of micro-parts,a vision detecting method lying on the image mosaicing has been brought forward in this paper,which is based on subpixel displacement interpolation and phase correlation.Two images have been taken as a sample.Cubic interpolation has been used to displace one image at first;cross power spectrum of the two images has been computed later;subpixel registration has been found out then,based on the maximum data of cross power spectrum distributing function;image interpolation is used to end the job.The experiment shows that: high accuracy,anti-noise and automatization can be achieved by this method.
